Asymmetry in emotional face: Its role in intensity of expression
(1995) Manas K. Mandal; Hari S. Asthana; Rakesh Pandey
Normal subjects rated expressiveness of two posed facial emotions, happy and sad; the photographs were stratified in terms of intensity of expression and were prepared in composite (right-right, left-left), normal, and mirror-reversed facial orientations. The left side of the face was more expressive for intermediate intensity expressions of happiness and for least intense expressions of happiness and sadness. The right side of the face was more expressive for most intense expressions of happiness and sadness. © 1995 Taylor & Francis Group, LLC.
Bilateral transfer deficit in schizophrenia
(1992) Manas K. Mandal; Shyam K. Singh; Hari S. Asthana; Pratima Srivastava
Right-handed chronic schizophrenics, left-handed normals, and right-handed normals were tested on a measure of bilateral transfer of motor skill in contralateral hands. Schizophrenics compared with normals showed significantly poor bilateral transfer of skill in terms of errors committed; the group difference was nonsignificant in terms of response time. Results suggested a breakdown in perceptual-motor coordination in schizophrenia. © 1992.
Cerebral laterality in affect and affective illness: A review
(1996) Manas K. Mandal; Hari S. Asthana; Rakesh Pandey; Suptendra Sarbadhikari
It is generally claimed that affect processing is a right hemisphere function. It is also claimed that right hemisphere dysfunction is characteristic of depressive illness. These claims are not accepted without controversy, and it has been found that the relationship between affect processing and affective illness in terms of intra- and interhemispheric role is not straightforward. Two types of studies are reviewed in this context: behavioral and electrophysiological. Potential confounding effects are discussed. © 1996 Taylor & Francis Group, LLC.
Degree of asymmetry in lateral preferences: Eye, foot, ear
(1992) Manas K. Mandal; Geetika Pandey; Shyam K. Singh; Hari S. Asthana
Lateral asymmetry in eye, foot, and ear preference was measured using a 15-item questionnaire administered to 442 subjects. Degree and magnitude of asymmetry were greatest for eye, followed by foot and ear. Intercorrelations of lateral preferences were all positive and significant. Two primary factors, eyedness and earedness, were established. © 1992 Taylor & Francis Group, LLC.
Effects of lesion variables and emotion type on the perception of facial emotion
(1999) Manas K. Mandal; Joan C. Borod; Hari S. Asthana; Aprajita Mohanty; S. Mohanty; Elissa Koff
The purpose of this study was to consider the effects of valence, motoric direction (i.e., approach/withdrawal), and arousal on the perception of facial emotion in patients with unilateral cortical lesions. We also examined the influence of lesion side, site, and size on emotional perception. Subjects were 30 right-hemisphere-damaged (RHD) and 30 left- hemisphere-damaged (LHD) male patients with focal lesions restricted primarily to the frontal, temporal, or parietal lobe. Patient groups were comparable on demographic and clinical neurological variables. Subjects were tested for their ability to match photographs of four facial emotional expressions: happiness, sadness, fear, and anger. Overall, RHD patients were significantly more impaired than LHD patients in perceiving facial emotion. Lesion side, but not site, was associated with motoric direction and valence dimensions. RHD patients had specific deficits relative to LHD patients in processing negative and withdrawal emotions; there were no group differences for positive/approach emotions. Lesion size was not significantly correlated with accuracy of emotional perception.
Hand Preference in India
(1992) Manas K. Mandai; Geetika Pandey; Shyam K. Singh; Hari S. Asthana
The degree of asymmetric handedness was measured by a 22‐item hand preference questionnaire in a sample of 442 Indian subjects. Factor analysis of the data for right‐handers yielded four item‐clusters: Gross activities, skilled activities (general), skilled activities (specific), and activities subject to social pressure. Identical analysis for left‐handers yielded three item‐clusters: Activities that are executed with difficulty, with ease, and with greater frequency. The degree of asymmetric handedness in right‐handers was positively (high) correlated with an index of social pressure against left‐hand use, especially for the items, writing and eating. The correlation was negative (moderate) in left‐handers, however, who had preferred the right hand for eating purposes. © 1992 International Union of Psychological Science
Hemifacial asymmetry in emotion expressions
(1998) Hari S. Asthana; Manas K. Mandal
We examined asymmetry in posed facial expression of emotions: happy and sad. Hemifacial composite photographs, left-left and right-right, were prepared and subjects rated these for intensity of expressed emotion. Overall, left-left composites were judged to have expressed emotions relatively more intensely than the right-right composites. The significant Sex x Emotion interaction revealed that female expressors were judged as mote expressive than male expressors in expressing sad facial emotion. Sex difference in expression of happy facial emotion was not significant.
Hemiregional variations in facial expression of emotions
(John Wiley and Sons Ltd., 1997) Hari S. Asthana; Manas K. Mandal
This study examined expressiveness of facial regions during posed expressions of two basic emotions: happy and sad. Two types of composite photographs were prepared: hemifacial composites of left-left (LL) or right-right (RR); and hemiregional composites involving a left-left composite in the upper part and a right-right composite in the lower part (LL/RR) of the face or vice versa (RR/LL). Participants ranked photographs of an emotion expression: normal orientation (RL) mirror reversed (LR), left facial composite (LL), right facial composite (RR) and hemiregional composites (RR/LL; LL/RR), in order of expressiveness. The hemiregional composite RR/LL was judged as most expressive followed by LL. The findings are explained in terms of the neuroanatomy of fibre projections from the left and right cerebral hemispheres to the facial muscles.
Hindi Adaptation and Psychometric Validation of Rivermead Post-Concussion Symptoms Questionnaire on Patients with Traumatic Brain Injury
(Oxford University Press, 2025) Akanksha Chaurasiya; Jay Kumar Ranjan; Nityanand Pandey; Hari S. Asthana
Background: The Rivermead Post-Concussion Symptoms Questionnaire (RPCSQ) is a widely used tool for assessing the pattern and severity of post–head injury symptoms, and has been translated and validated in various languages. However, a Hindi version of this questionnaire is not yet available. Therefore, the present study aimed to adapt the RPCSQ into Hindi and examine its factorial structure along with its psychometric properties. Method: The original English version of RPCSQ was adapted into Hindi by using the cross-cultural adaptation process. The final adapted Hindi version of RPCSQ (RPCSQ-H) was administered on traumatic brain injury (TBI) participants to assess its reliability, factor structure, discriminant validity, construct validity, and temporal stability of scale. Result: The psychometric evaluation of the scale yielded an acceptable Cronbach’s α coefficient of 0.768. The temporal stability of RPCSQ-H was significant at the acute stage, with test–retest coefficients of 0.713 and 0.615 after 7 days and 14 days, respectively. Additionally, the results supported a six-factor model of the RPCSQ-H with good convergent validity, factor reliability, and discriminant validity. Conclusion: The RPCSQ-H demonstrates strong reliability and validity along with good psychometric to assess post–head injury symptoms in Hindi-speaking patients with TBI. © The Author(s) 2025.

Judgment of facial expression of emotion in unilateral brain-damaged patients
(1993) Manas K. Mandal; Hari S. Asthana; Shiv C. Tandon
Patients with unilateral brain damage and normal controls were asked to give (1) inter-emotion judgment within the photographs of six facial emotions in terms of mutual similarities, and (2) intra-emotion judgment within the hemifacial composite photographs of an emotion in terms of intensity of expression. Right brain-damaged patients could differentiate between the emotion of happiness and all other emotions. Left brain-damaged patients differentiated between aroused-nonaroused emotions. Normal controls differentiated between positive-negative as well as aroused-nonaroused emotions. Left-left facial composites were judged to have expressed more intensely than right-right facial composites or normal/mirror-reversed facial orientations of emotions (except fear) by any group (p > .05). © 1993.
Matching top-bottom parts of facial expressions by brain-damaged patients
(1991) Hari S. Asthana; Manas K. Mandal; Shiv C. Tandon; Sanjay Asthana
Patients with focal brain-damage, right/left hemisphere-damage (RHD/LHD) and anterior/posterior region-damage (ARD/PRD), and normal controls (NC) were asked to match photographs of top-bottom facial parts expressing different emotions, positive (happy, surprise), negative-aroused (fear, anger), negative-nonaroused (sad, disgust). The LHD patients performed significantly worse than the RHD patients, and the ARD patients were significantly worse than the PRD patients, in the perceptual-matching task with affective stimuli. NC subjects performed significantly better than any of the brain damaged sub-groups. © 1991 Rapid Communications of Oxford Ltd.
Neurocognitive and Affective Sequelae Following Complicated Mild and Moderate Traumatic Brain Injury: A Case Series
(NLM (Medline), 2021) Akanksha Chaurasiya; Nityanand Pandey; Jay K. Ranjan; Hari S. Asthana
Background: Traumatic brain injury (TBI) leads to various sequelae that affect the day-to-day functioning of patients. However, there is a dearth of studies investigating these sequelae in complicated mild TBI and moderate TBI patients. Objective: The prime objective of the present study was to present the neurocognitive and affective profile of complicated mild and moderate TBI patients along with to compare the neurocognitive and affective sequelae in patients with complicated mild and moderate TBI. Materials and Methods: Twenty-two patients with complicated mild TBI and 17 patients with Moderate TBI, each with an intracranial lesion were recruited from level 1 trauma center in Varanasi. All patients were assessed with neurocognitive measures, Rivermead Post Concussive Symptoms Questionnaire, and Hospital Anxiety and Depression Scale. The patients' profiles were presented as clinical series using descriptive analysis. Further, comparison was done by using the Chi-square test and Fisher's exact test. Results: Findings revealed that complicated mild TBI patients reported significantly higher psychological distress and post head injury symptoms in comparison to patients with moderate TBI. Further, the complicated mild TBI and moderate TBI groups showed differences with respect to verbal fluency, mental speed, and flexibility tasks. Conclusions: Complicated mild TBI and moderate TBI groups have not differed significantly on most of the cognitive tasks. Furthermore, affective symptoms were found more prominent in complicated mild TBI group as compared to the moderate TBI group.
Prevalence of Head Injury in India: A Systematic Review and Meta-analysis of Cross-sectional Community-based Surveys
(SAGE Publications Inc., 2025) Saishree; Jay Kumar Ranjan; Hari S. Asthana; Nityanand Pandey
Background: Head injury (HI) causes a wide range of psychological symptoms, such as cognitive deficits and mood changes, leading to significant disability. Although a few studies have explored the prevalence of HI in India. However, none of the meta-analytical studies reported the estimation of the prevalence of HI in India based on cross-sectional community surveys. Summary: A systematic review search was conducted on journal hosting sites, namely EBSCOhost, Google Scholar, Ovid, PubMed, and Web of Science, complying with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Cross-sectional Indian studies reporting the prevalence of HI in India were included in the present study. The risk of bias was assessed using the Risk of Bias Tool for Prevalence Studies. The meta-analysis was conducted using ‘meta’ and ‘dmetar’ packages through R software (4.4.0). A total of 17 studies surveyed 85,720 people, of whom 921 suffered from HI. The results showed an HI prevalence of 25.7 per thousand people in India. Subgroup analysis revealed a higher prevalence of HI among females (91.1 per 1,000) in comparison to males (85.1 per 1,000). Additionally, subgroup analysis of domicile revealed a higher HI prevalence among those from urban areas (29.5 per 1,000) than among those from rural areas (22.4 per 1,000). Key Message: This study highlights the substantial burden of HI in India and the associated disparities in gender and domicile. The findings will be helpful to health professionals and policymakers in making informed decisions regarding the preventive aspects of HI in India. © The Author(s) 2025.

Right hemisphere damage impairs the ability to process emotional expressions of unusual faces
(1998) Manas K. Mandal; Hari S. Asthana; Samya Maitra
Patients with focal brain damage, right and left hemisphere damage, and nonpatient controls were asked to match photographs of emotion expressions that were depicted in unusual (line drawings, strange, and schematic) and normal (usual) representations of faces with the target emotion expressions of normal face. Nonpatient controls were significantly superior to right hemisphere damaged patients in matching photographs of emotion expressions that were depicted in line drawings of normal face and schematic face.
Visuospatial and affect recognition deficit in depression
(Elsevier, 1998) Hari S. Asthana; Manas K. Mandal; Hitesh Khurana; S. Haque-Nizamie
Background: Theorists differ in their opinion whether interpersonal difficulties in depression is associated more with perceptual impairment or with emotional bias. The present study intended to resolve such differences of opinion. Method: Major depressives, general medical patients, and non- patient controls were administered three visuospatial and two affective tasks to examine the nature of performance deficit associated with each group. Results: Major depressives were found significantly impaired in both visuospatial and affective tasks in comparison to general medical patients, who in turn, were impaired than non-patient controls. Conclusion: Major depressives' perceptual deficit is pervasive and not specific to affective categories. Limitation: The study could have been more informative if more psychiatric groups had been included as subjects. Clinical Relevance: Improvement in depressives' ability for visuospatial and affective tasks may be considered as a marker of their clinical improvement.
